Halfway Between 45 and 628

When you ask "What number is halfway between 45 and 628?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=45 and Y=628.

Halfway Between Line

To find the number halfway between 45 and 628, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 628 into our formula, we get:

(45 + 628)/2 = 336.5

Thus, the number halfway between 45 and 628 is 336.5.

To check that our answer is correct, we subtract 45 from 336.5 and subtract 336.5 from 628 and compare the two numbers:

336.5 - 45 = 291.5
628 - 336.5 = 291.5

As you can see, the halfway number is 291.5 higher than 45 and 291.5 lower than 628. Therefore, our halfway between answer of 336.5 above is correct.
